The infotronics department of HES-SO Valais is preparing a Master course on high performance signal acquisition and processing. This course will be illustrated with an example linked to a very small satellite, a CubeSat named SwissCube. An Attitude Control and Determination System (ACDS) will be implemented. The goal of this thesis is to realize a demonstrator of a one liter cube levitating in a magnetic field. The weight of this cube shall not exceed 400 g. This cube shall be able to control its vertical position (translation in the vertical axe Z) and its azimuth (rotation in the horizontal plane x,y) in order to secure its stability. The project is composed of two parts: the horizontal one which is responsible for the rotation of the cube and the angle measurement, the vertical one which implements a distance measurement between the magnetic ceiling and the cube as well as a magnetic field regulation in order to control its vertical position. No wire will be used, which indicates that the cube itself will send the necessary correction information to the control unit throughout a Radio Frequency (RF) link. Like a real CubeSat, this cube should also have low power consumption: only one or two charges of the internal accumulator a day shall be necessary.
